[Debian-med-packaging] Packaging R igraph for Debian

[Gábor Csárdi]

Hi Andreas,

the first one is an issue that has come up a couple of times so far
with ARPACK, but I don't know how to fix it in this case, I can't seem
to be able to reproduce it.

The second one I can reproduce, and it will be fixed in the next
version of igraph.

Best,
Gabor
